I narrowed the search down to history books and found 33 results. What interested me was that the top book was about Dracula and his life and times. It seems to be a good book, and I will probably read it on Kindle. The reviews and generally positive so that seems to be a point in its favour.
Transylvania and Romania.
Except that writing about this land and about Vlad Tepes means dealing with Dracula.
